I have a large collection of .flac files on my PC. However, recently I have noticed a few were not in the play list in Foobar2000. I did a full scan of all my files and it turns out a little more than 20 of t hem are 'corrupt'. I don't know how this has happened (maybe something has written bad tags to them, maybe Ableton Live 6 has fucked them up). However I would like to know if they can be repaired by some means as I live in Italy and my record collection is in the UK. Also, is there some way to tell how they became corrupt?
